SELF-CLOSING FAUCET.

SPECIFICATION forming part of Letters Patent No. 401,288, dated April 9, 1889.

Application filed September l2, 1888. Serial No. 285,261. (No model.)

i which improvement is fully set forth in the following specification and accompanying drawings.

My invention consists of a self-closing faucet constructed substantially as hereinafterset forth and claimed, whereby the same is readily operated to be opened and closed, and should the handle break the faucet remains closed.

Figure l represents a partial side elevation and partial vertical section of a faucet embodying my invention. Fig. 2 represents a front end view, partly sectional.

Similar letters of reference indicate corresponding parts in the two figures.

Referring to the drawings, A represents the shell of the faucet, the same having at its discharge end a chamber, B, which is screwthreaded, as at C, for the engagement of a nut or thimble, D, which is screw-threaded, as at D D3, and formed with a flange, D2, between said screw-threads. To the thimble at D3 is screwed the collar E, within which is freely litted the tube or barrel F, which also passes freely through said thimble D. The upper end of said tube is closed by a head, F', which seats itself upon the top of the thimble, and has below said head a series of openings, F2, which when the tube is in normal position are surrounded by the inner wall of the thimble D and thereby closed.

G represents the discharge spout or nozzle, which is interiorly threaded, as at G', for engagement with threads F3 on the exterior of the lower end of the tube F. Within the chamber B is a spring, H, which bears upon the head of the tube for holding the latter in lowermost or closed position. Packing E is interposed between the collar E and tube F, at the base of the thimbleD, for preventing leaking at the joint of said parts, and a washer or packing is interposed between the ange D2 of the thimble and base of the chamber B for preventing leaking at the joint The outer wall of the chamber f lines, Fig. l. This raises the nozzle G, and with it the tube F, whereby the openings F2 of the latter are raised above the thimble D. Fluid may now liow from the chamber B through said openings F2 into the tube F, and so escape from the latter. As soon as the' handle is let go, the spring H, previously compressed or contracted, is now operative, and byits expansion forces the tube downwardly or outwardly, causing the openings F2 to be covered by the inner wall of the thimble D, whereby the faucet is quickly closed and discharge of the fluid stopped.

It is evident that should the handle break at any time it will not release the tube. Consequently the faucet remains closed, and improper discharge of fluid is thereby prevented.

The upper portion of the nozzle G is recessed or set out from the lower portion of the collar E, forming an airpassage, a, which communicates with vents b in the tube F, by which provision air may enter said tube to cause the same to drain when closed.

The handle may be placed at the top of the shell, instead of at the side, as shown, and I do not limit myself to the location of the same.

The annulus J3 freely receives the upper end of the nozzle G. Consequently the latter may be raised by pressing the mouth of the bottle against the same, thus opening the faucet and allowing the iiuid to enter the bottle. In each case the handle is not used, and consequently may be omitted.

I am aware that it is not new to construct a self-closing faucet having a shell with chamber, a tube projecting from and movable in said chamber, a spring in said chamber bearing against said tube, and means secured to said shell for operating said tube, the said tube having openings in its side, whereby communication is had between the chamber and the interior of the tube; but I am not aware that the construction herein set forth IOO - and claimed is old, wherein a thimble with a flanged portion is secured to the chamber and a sleeve secured to the lower end of the thimble, thus furnishing alengthened bearing for said tube that is easily replaced in case of Wear, and also permitting the easy separation of the tube Afrom the chamber for cleansing purposes; neither is it believed to be old to provide the tube with a vent or vents coinciding with the lower edge of the sleeve embracing the tube, so that the said vent is open when the cock is closed.

Having thus described my invention, What claim as new, and desire to secure by Letters Patent, is-

l. A self-closing faucet consisting of a shell with a chamber, a thimble and sleeve connected to the shell, a tube Within said thimble and sleeve having perforations affording communication between the chamber and the interior of the tube, and side vents opening the interior of the tube to the atmosphere, a spring Within the tube bearing` against the head of the tube, and a nozzle connected to lthe tube, the said vents coinciding With the lower edge of the said sleeve when the faucet is closed, substantially as described.

2. A self-closing faucet having a shell With a chamber, a sliding tube projecting from said shell and having side vents and a bore, the

latter communicating with the said chamber ,the said vents being uncovered when the cock is closed, said parts being combined substantially as described.

3. A self-closing faucet consisting of the shell A, with chamber B therein, the thimble D, secured to shell A, the collar E, secured to said thimble, the sliding tube F, having a closed head, F', With side openings, F2, below said head, said head having a seat on the top of said thimble D, the spring H in said chamber B bearing` against said sliding tube, the nozzle G, secured to said tube F, and the pivoted handle J, with link J2 and annulus J3, said parts being combined substantially as described.
